Ampicillin is used as a preventive therapy as well as for the treatment of respiratory tract infections, urinary tract infections and salmonella infections.
How it works
Ampicillin is a penicillin antibiotic that damages the bacterial cell wall to eliminate the bacteria.
Taking Ampicillin & the right dosage
Ampicillin may be taken with or without a meal.
The extended release pill should not be crushed or chewed. It must be swallowed whole.
Ampicillin must be consumed for the complete prescribed time duration. You may notice that your symptoms may improve before the prescribed duration is over or the infection is cleared. But do not alter the dose or the schedule without consulting your doctor.
Store Ampicillin in a cool and dark place at room temperature. Do not store it in a place where it can get exposed to direct sunlight or moisture.
Keep it away from children and pets.
